1. Yes society is against other people doing anything pleasurable. Anything. Relationships are required to be combat, whether it is cuddling your children (DO NOT have intercourse with them) and a peaceful bond with your spouse, to mutually beneficial work relations and neighbors who don't scream at you with threats. And especially a government for the people, not actively extorting and violating survivability. So much so that people will make themselves miserable to be sure others are not having fun. Just having an enjoyable hobby is reason to be ridiculed by this culture (both western and japanese).
2. Having lots of sex it just deranged behavior due to having nothing else pleasurable in life. Sex is most enjoyable with a compatible partner when both are consenting and willing. Height of passion in one night is worth far more than running around sticking your dick in everything for a year, trust me on this one... even better that she wants it often, it keeps me going through the living hell of this world every week.
3. Risk seeking behavior is stupid, literally and measurable. Intelligent educated people take fewer extreme risk actions. Physical, financial, relationship, etc. Can't afford the cost and time to raise children right, smart people have fewer children, just look at the ghettos and Elon Musk. Notice how bikers racing in traffic and riding on one wheel are not engineers, doctors, and inventors at the top of their field?
